triumph 350 and 500 models did away with separate transmissions in 1957. 650's in 63. Forward controls are used on all choppers to gain legroom. The 5 speed conversion isn't a bolt in, it requires some thought. I worked at 2 triumph shops, and know a little about this. Please get your facts straight. When using a 5 speed, gear up, as the 1st gear is unusably low. This gives you more 5th gear cruising(lower rpm). Shifting was on the right until 1974 models.
